For trial access (request by emailing
lc@masterdata.com),
you will be given access to four current
datafiles. These are not sample files. They
are the actual files for the day. Click on
the file name to download:

Constituents-3.csv:
This file is a portion of the entire
file immediately above with exactly
the same format. As with the above
file, it is updated daily. This
file is small enough to open in earlier
versions of Microsoft Excel (about 60,000
rows). There are currently
five to six of this type of file
generated daily (1 through 6).

SPY.csv: This
file contains constituent data for the
SPDR S&P 500 ETF (SPY). It
is updated daily. Constituent
lists are available both in one large
file containing all lists as well as
individual lists like this one.
